We need a new comforter/duvet for our bed because we both hate the one we bought when we bought our king size bed.

I like the current color--it's a navy blue. But it's way too thick (WAY too hot in summer and even too hot for much of the winter) and the worst part is...even though it was an expensive comforter, it's made out of polyester. =( Which like, sticks to the callouses on our feet or on our dry hands in winter, and we just generally hate it.

So lately, we've been using my husband's old bachelor pad comforter, which is a hideous shade of green and only a queen size, BUT is just the right weight and a supersoft 100% cotton calvin klein comforter.

So now I'm looking for a 100% cotton comforter or duvet cover, that is super soft, in the dark blue/navy color family with a slightly modern look (no florals, no plaid, no totally solids). I saw some at West Elm that looked promising, but they were stiff and rough IRL.

Suggestions? Pictures below are our current hated comforter and the coverlet we liked at West Elm (but that ended up being too rough).
